Dislocation (Corrosion)

A linear imperfection in a crystalline array of atoms. Two basic types are recognized: (1) an edge dislocation corresponds to the row of mismatched atoms along the edge formed by an extra, partial plane of atoms within the body of a crystal; (2) a screw dislocation corresponds to the axis of a spiral structure in a crystal, characterized by a distortion that joins normally parallel planes together to form a continuous helical ramp (with a pitch of one interplanar distance) winding about the dislocation. Most prevalent is the so-called mixed dislocation, which is any combination of an edge dislocation and a screw dislocation.

Dislocation (Health)

Occurs when extreme force is put on a ligament causing the two bone ends to separate. Dislocations can also affect a joint, the point where two or more bones come together. The joint is created as a "ball-and-socket" joint. A dislocated joint causes the head of the bone (ball) to partially or completely come out of the socket.

Dislocation (Medical)

Displacement of the two bones in a joint

Dislocation (Metal)

A linear defect in the structure of a crystal.
